The Fighting Irish will play five football games per year against ACC teams, on rotation. Adding those non-conference games to a nine-game league slate created too much scheduling inflexibility for some tastes.

For example, consider Clemson, which opposed the nine-game ACC schedule from the start. It has an annual non-conference contest against state rival South Carolina, so in years the Tigers also played Notre Dame, 11 of their 12 regular-season games would have been locked in.

Same holds for Florida State and Georgia Tech, who have annual non-league dates with Florida and Georgia, respectively.

With next year’s arrival of Syracuse and Pittsburgh, the ACC will have 14 full-time members split into seven-team divisions for football. Schools will play their six division rivals annually, plus one permanent crossover opponent – Maryland for Virginia, Boston College for Virginia Tech.

That translates to facing the other six teams from the opposite division once every six years, once every 12 at home. So athletes will play their entire career without playing some schools in their own conference, and marquee programs from the Atlantic Division such as Florida State and Clemson will visit Virginia Tech and Virginia only once every 12 years.

With a nine-game conference schedule, schools would have faced the other six from the opposite division once every three years, once every six at home.

Odd thing is, with Notre Dame rotating five ACC opponents, teams will face the Fighting Irish twice as often as they do six full-time conference members.

Conversely, trimming the league schedule back to eight games, might tempt Notre Dame to further consider full ACC membership. That would leave the Irish four non-conference games and more space to continue traditional rivalries with the likes of Southern California and Navy.

Full membership for Notre Dame would be the only reason for the ACC to search for a 16th school.

Wednesday's announcement also means the athletic directors at each of the ACC's 14 schools are scrambling to add a non-conference game for next season, and beyond.

* Wednesday’s other scheduling news from the ACC was expected: When Notre Dame arrives as the 15th basketball school, teams will have two partners they play twice every season.

In addition to four annual games against partners, the remaining 14 conference games will include two each with two rotating opponents and one each against the remaining 10, five home and five away.

The partners are:

Boston College: Notre Dame and Syracuse.

Clemson: Florida State and Georgia Tech.

Duke: North Carolina and Wake Forest.

Florida State: Clemson and Miami.

Georgia Tech: Clemson and Notre Dame.

Maryland: Pitt and Virginia.

Miami: Florida State and Virginia Tech.

North Carolina: Duke and North Carolina State.

N.C. State: North Carolina and Wake Forest.

Notre Dame: Boston College and Georgia Tech.

Pitt: Maryland and Syracuse.

Syracuse: Boston College and Pitt.

Virginia: Virginia Tech and Maryland.

Virginia Tech: Virginia and Miami.

Wake Forest: Duke and N.C. State.

The ACC tournament will start with three first-round games Wednesday between seeds 10-15. Those winners join seeds 5-9 for Thursday’s four second-round games. The top four seeds have byes into Friday’s quarterfinals.

Also Wednesday, the ACC decided that its 12 highest-ranked basketball teams in the Rating Percentage Index will compete the following season in the ACC-Big Ten Challenge. The Big Ten has 12 members.
